A new key detail has emerged in the foiled underwear bomb plot: NPR's Dina Temple-Raston reports that a CIA informant posed as a suicide bomber in order to persuade the al-Qaida branch in Yemen to hand over a new, more sophisticated underwear bomb.
The latest plot to bomb a U.S. airliner has been foiled, but U.S. intelligence officials have described the bomb as a sophisticated device that's believed to be the work of al-Qaida in the Arabian Peninsula. Many details are still not available, but here's what is and isn't known so far:
The White House and FBI have confirmed al-Qaida attempted to target a plane bound for the United States. All indications are the plan was conceived by al-Qaida's arm in Yemen. But officials say the plot was foiled before it was any threat to the public.
U.S. authorities say they have foiled a terrorist plot to target an airliner. A suicide bomber was planning to bring down a plane headed to the United States. The Associated Press first reported the story. Al-Qaida's affiliate group in Yemen is believed to be behind the plot, which national security officials say had not advanced far enough, that the suspect bought plane tickets or tried to board a plane.
